all fridges have a small drain hole at the bottom of the back wall inside the cabinet. to drain away water during defrost cycle which all fridges do automatic every 6-8 hours. make sure this hole is not blocked. use something smaller than diameter of hole to unblock. dont worry where this leads to. the fridge will collect this water near some hot pipe work or the compressor and burn off the water during normal operation. make sure fridge is more or less level with a very slight tilt back so water will naturally flow towards hole.
